Prologue: Warming Up with Cross Ratios, and the Definition of Moduli Space,Throughout this book we work over the field of complex numbers. When we speak of schemes we mean schemes of finite type over Spec ℂ.我正派 发表于 2025-3-25 09:15:24

,Gromov—Witten Invariants,The intersection numbers resulting from an ideal transverse situation as in Proposition 3.4.3. are the (genus-0) .. In Section 4.2 we establish the basic properties of Gromov-Witten invariants, and in 4.3 and 4.4 we describe recursive relations among them, allowing for their computation.终点 发表于 2025-3-25 22:51:56

Quantum Cohomology,define a . on .. Kontsevich’s formula and the other recursions we found in Chapter 4, are then interpreted as partial differential equations for the Gromov-Witten potential. The striking fact about all these equations is that they amount to the associativity of the quantum product! In particular, Koconjunctivitis 发表于 2025-3-26 09:46:31
